This paper examines the possibility of financial contagion from the Russian stock market toward 18 global markets due to the international sanctions resulting from Russia's actions in Crimea. We develop a z-transform dynamic heteroskedastic procedure to determine the potential degrees of contagion and explore possible volatility spillovers. Among our main results, the Russian market substantially decoupled from the vast majority of world markets, irrespectively of the strength of economic ties between Russia and the corresponding countries. Yet, the crisis was characterized by large transmissions of volatility associated with the Russian market, particularly in emerging and frontier economies.JEL classification: F30, E30, C32, F42.
